What does calibration involve with measurement instruments?

Calibration involves adjusting and verifying the accuracy of measurement instruments against known standards. This process is crucial because it ensures that the instruments provide correct and reliable measurements, which are fundamental for the effective operation of control systems. During calibration, a device's output is compared to a reference or standard measurement. If discrepancies are found, adjustments are made to align the instrument's readings with the standard, thereby enhancing the reliability and accuracy of data collected during operations. This process is fundamental in various applications, including manufacturing, laboratory settings, and field measurements, ultimately ensuring that systems operate consistently within their designed parameters.
